Question

A 2% decrease is written as

A 30% increase is written as

Answer 1

100% - 2% = 98%

Or 100% x 0.98 = 98%

100% - 30% = 70%

Or

100% x 0.7 = 70%

Answer : 0.98 & 0.7

Thus, any number/price multiplied by these decimal multipilers - automatically, will give you the decreased values of the original values.)

For example, a £300 bag is on a sale for 2% off, how much does it cost?

£300 x 0.98 = £294 (final price of the bag)

Hope this helps!
